It used to be that we would encrypt our home internet wifi with passwords to keep others from using our bandwidth, but now all your home tech may actually do the exact opposite. 'Amazon Sidewalk' is a new feature rolling out to users of Amazon products which will share your internet with your neighbors. What Is Amazon Sidewalk? I don't have any Amazon devices in my house. Instead I have Google Home which ties multiple routers in my home together so I can get full coverage around my house without any interruptions. The 'Amazon Sidewalk' idea sounds like a neighborhood sized version of what I have. So, instead of my router just sharing with my other home routers, Sidewalk will share the internet with other homes' routers and devices when they lose connectivity.
